(SOLVED!) Loud transmission clunk
Hi all,
I have about 130,000 miles on my 2013 and I've just developed this ultra loud transmission clunk when making right turns only under acceleration. This noise is not there when I have the clutch in and take a right turn. My throwout bearing is about to go out again based on the compressed air noise it makes when I put my foot on the clutch, but I think this issue is unrelated to the throw out bearing. I had my diff/transmission serviced 10k miles ago with Motul, no signs of leaks or anything. I checked my transmission mount and everything looked fine and all the bolts were properly torqued. When I rev the car in Neutral I don't hear any noises so that may rule out engine mounts. The noise is coming from directly in front/below the shifter. Anyone have any idea on what this noise could be??? Not only is it loud, but it shakes the whole car violently. TIA.

Also noticed a fluid coming out of my driver's side axle. Looks like the CV joint.
Is this something to be worried about? Passenger side looks normal I guess: |

First the boot cracked. Then the lube spun out. Now the CV joint is shot.
Textbook failure. [ame]https://www.youtube.com/watch?v=xh6UrAzf4aE[/ame] Use this format.

I think the slight difference in sound is due to a combination of slop in the failed CV joint along with the locking action of the Torsen.

I'm wondering if my last track day tore a boot and I'm now starting to feel the repercussions. Will this potentially damage the differential? |

Until you fix it, try to plan your corners so you coast through them as much as you can.

I have an appointment at an 86 shop next Wednesday, but I’ll have it looked at before then. For it to make so much noise, the joint must be totally void of grease...but it would make sense how a sharp right turn under throttle would upset the driver side axle as it’s supporting a ton of weight from the car. Looks like $320 for an axle fml. |

Meh. That's about right. Stay away from the rebuilt ones. I learned that lesson the hard way. :/

Woh.... crunchy cv bearing.
I'll concur with everyone and say it's your axles. But...if it was me I'll just rebuild them from good axle shop. I'll just make sure they come with a nice warranty. $300 is a bit pricy. But at the end of the day it's your wallet not mine.

You can try hitting up CL or facebook market place for a car being parted out. I have a spare set of CV's I picked up that way.
